14a is located between air port 12a and the first combustion gas spout 13a.For example, as shown in figure 4, the second combustion gas spout 14a and air
Spout 12a and the setting of the first combustion gas interval spout 13a, the second combustion gas ejected as a result, by the second combustion gas spout 14a can
Preferably to organize to pass through air, the first combustion gas and the second combustion gas in combustion with the burning of air, the first combustion gas
Jet stream, to realize High Temperature Air Combustion, and the layout of burner 100 is more compact, is saved with rolling up the flue gas of suction fuel burning
The occupied area of burner 100 has been saved, to reduce the drag losses in 100 heat transfer process of burner, has been improved
Temperature transmission efficiency.
In an alternate embodiment of the present invention where, the shape of the second combustion gas spout 14a is circle.Is facilitated as a result,
The processing of two combustion gas spout 14a, and facilitate the adjusting of the flow from the second combustion gas spout 14a the second combustion gas flowed out.
Still optionally further, as shown in Figure 1, the central axis of the central axis of air port 12a and the first combustion gas spout 13a
Angle between line is α, and wherein α meets: 5 °≤α≤30 °.Pass through the central axis and first of setting air port 12a as a result,
Angle between the central axis of combustion gas spout 13a, the flatness of adjustable flame combustion, so that classification combustion be better achieved
It burns.
Preferably, the angle α between the central axis of air port 12a and the central axis of the first combustion gas spout 13a=
10 °, at this point, the flatness of air and the first combustion gas mixing burned flame is best, the optimization of fractional combustion is realized, is reached
The purpose of environmental protection.
In one embodiment of the invention, separate first heat storage of air port 12a and the first combustion gas spout 13a
121 and second heat storage 131 side be equipped with muffle set 2, muffle set 2 with air port 12a and the first interval combustion gas spout 13a
Setting.For example, muffle set 2 can be with as shown in Figure 1, the right side of air port 12a and the first combustion gas spout 13a are equipped with muffle set 2

Burner 100 is during installation, according to absolute altitude of the radiant tube 3 on furnace wall 4, first by 3 surrounding of radiant tube
It is sealingly mounted on furnace wall 4, and will radiation pipe connections 31 and the continuously welding of furnace wall 4.Secondly installation muffle set 2, by radiant tube 3
In sundries clean out, muffle set 2 is horizontally arranged in radiant tube 3,3 left side of threshold value radiant tube of muffle set 2
Distance can be 474mm, in installation burner block 15, guarantee that burner block 15 and muffle cover 2 spacing between 20mm~50mm, with
It avoids burner block 15 that thermal expansion occurs and squeezes muffle set 2, play the role of protecting muffle set 2, and be arranged in burner block 15
Third heat storage 151 and the 4th heat storage 152, and third heat storage 151 and the 4th heat storage 152 are high-temperature thermal storage body.So
Afterwards by air regenerator 12, the first regenerator gas room 13 and radiant tube 3 by flanged joint, and pass through the sealing of 3mm~5mm thickness
Asbestos washer realizes sealing.The first heat storage 121 and second is respectively set in air regenerator 12, the first regenerator gas room 13
Heat storage 131, and the first heat storage 121 and the second heat storage 131 are low-temperature heat accumulating body.Wherein, the first heat storage 121,
Low temperature grid can be installed in two heat storages 131, third heat storage 151 and the 4th heat storage 152, to realize to the first accumulation of heat
The limit of body 121, the second heat storage 131, third heat storage 151 and the 4th heat storage 152, low temperature grid can be pacified by bolt
On burner 100.Then burner cover board 112 is installed again, igniter burner 11 is mounted on burner 100, is pacified
It is noted that sealing when filling burner cover board 112.At this point it is possible to will igniting air intlet 11a and igniting fuel gas inlet with plastic cloth etc.
11b is sealed up, in order to avoid fall into sundries during subsequent construction and block igniting air intlet 11a and igniting fuel gas inlet 11b, shadow
Ring the igniting of burner 100.When igniter burner 11 is installed, it is broken should first to check whether the ignitor 111 of igniter burner 11 has
Damage, it is ensured that after 111 no problem of ignitor, then carry out the installation of igniter burner 11, and pay attention to sealing.
It is connected between two air intlet 12b the first reversing arrangement such as four-way reversing valve (not shown go out), two the
The second reversing arrangement such as four-way reversing valve (not shown go out) is connected between one fuel gas inlet 13b.As shown in Figure 1, working as air
From the air intlet 12b of the fuel element 1 of top, the first combustion gas from the first fuel gas inlet 13b of the fuel element 1 of top,
When two combustion gas flow into burner 100 from the second fuel gas inlet 14b of the fuel element 1 of top, the sky of the fuel element 1 of lower section
Gas import 12b, the first fuel gas inlet 13b are exhanst gas outlet；Conversely, by adjusting the first reversing arrangement and the second commutation dress
Set, when the fuel element 1 of air from below air intlet 12b, the fuel element 1 of the first combustion gas from below the first combustion gas into
The second fuel gas inlet 14b when flowing into burner 100 of mouthful 13b, the fuel element 1 of the second combustion gas from below, the burning of top
The air intlet 12b of unit 1, the first fuel gas inlet 13b are exhanst gas outlet.
When starting burner 100, igniting air intlet 11a and the igniting combustion gas of one of fuel element 1 are first passed through
Import 11b each leads into combustion air and combustion-supporting combustion gas into burner 100, and is lighted by ignitor 111, right
First heat storage 121, the second heat storage 131, third heat storage 151 and the 4th heat storage 152 are heated.To its flameholding
Afterwards, according to the thermic load of burner 100, by air intlet 12b, the first fuel gas inlet 13b and the second fuel gas inlet 14b to
A certain amount of air, the first combustion gas and the second combustion gas are passed through in burner 100, air passes through the first heat storage 121 and third
Heat storage 151 is preheated to 800 DEG C~900 DEG C (only than few 100 DEG C of temperature or so in the heating equipments such as heating furnace) into combustion
It bakes bricks 15, and is sprayed from air port 12a, the first combustion gas is preheated by the second heat storage 131 and the 4th heat storage 152, and
It is sprayed from the first combustion gas spout 13a, the second combustion gas, which is not warmed up, directly sprays through the second fuel gas conduit 14 from the second combustion gas spout 14a
Out, the high-temperature flue gas of air, the first combustion gas and the second combustion gas mixing after-combustion, generation enters radiant tube 3 by muffle set 2
Interior, to heat to radiant tube 3, then high-temperature flue gas enters another fuel element 1, and to the first of the fuel element 1
Heat storage 121, the second heat storage 131, third heat storage 151 and the 4th heat storage 152 are heated, finally from the fuel element
1 air intlet 12b and the first fuel gas inlet 13b discharge, the temperature of flue gas falls below 180 DEG C or less at this time.One timing of operation
Between after, it is contemplated that the factors such as cost can cut off the conveying of the second combustion gas.After the above process is stable, it can close
The igniter burner 11 of one of fuel element 1 is stated, and starts the igniter burner 11 of another above-mentioned fuel element 1, thus real
Show the reversing combustion of burner 100, to realize the limit recycling of fume afterheat, improves the utilization rate of the energy.
